More likely it's above their intellectual ability to discuss math or science. Most modern philosophers read like third-rate mathematicians who haven't bothered to carefully work out what they really mean.
The names in credentialed, professional philosophy have--for the most part, most of the time--impeccable reasoning. The majority of students have little reasoning, and the little they have is flawed. We ought to distinguish between real philosophers and those extracurriculars who use some of the form of philosophic process, but without the depth, breadth, and skill of real philosophers.
"A philosophy is characterized more by the formulation of its problems than by its solution of them." - Suzanne K. Langer
